Offers full-screen terminal multiplexing with independent windows, VT100 emulation, scrollback, and copy-paste. Supports ANSI standards, detaching, and persistent background process execution for shells or commands across Unix-like systems.

Universal Rust multiplexer for the agentic era: detachable, scriptable, and inspectable, with a tmux-compatible CLI, daemon-backed SDK, and native Ratatui integration.
